Yes, there are such fanfics in the Harry Potter fandom. Some fans like to explore different relationship dynamics and create unique storylines where Sirius and Remus are Harry's fathers in a romantic relationship. These fanfics often play with the idea of an alternative family structure for Harry within the magical world.
A plotline could involve Sirius and Remus trying to raise Harry while dealing with their own personal traumas. Sirius with his time in Azkaban and Remus with his lycanthropy. They could also face challenges from the Ministry of Magic, who might be suspicious of their non - traditional family unit. And of course, there could be a love story arc between Sirius and Remus that weaves in and out of Harry's upbringing.
One common theme is family. It explores how a non - traditional family structure with two fathers can function. Another theme is acceptance, both within the family and in the wizarding community. Also, the fanfics often deal with the challenges of raising Harry in this new setup.
If Sirius and Remus were Harry's fathers in a fanfic, it would change a lot. For one, Harry would have two dads who are very different yet equally loving. Sirius being an Animagus and Remus a werewolf would expose Harry to a different side of the wizarding world from a young age. Also, their relationship would add a whole new layer of depth to Harry's character development as he navigates his own identity within this unique family structure.
I really like 'A Ray of Hope in the Darkness'. In this fanfic, Sirius is depressed after the events that have befallen him. Remus is portrayed as a very patient and loving character. He slowly helps Sirius heal by being there for him, and the story is full of emotional moments that will make you feel for both characters.
Friendship is a very common theme. Their deep bond as friends is often explored, how they support each other through difficult times at Hogwarts and later in life.
Friendship is also a big theme. Their unique friendship, which is a blend of mischief and deep understanding, is often the focus. Fics might show how they support each other through difficult times like the war or personal struggles.
The idea of redemption can also be a theme. For example, Sirius' journey to redeem himself in some fanfics after his time in Azkaban. Also, the theme of secrecy, as they have to keep some things about themselves (like Remus' condition) a secret from the outside world, which adds an element of mystery and drama to the fanfics.
A good 'Remus x Sirius' fanfic with a depressed Sirius should first and foremost have a deep understanding of the characters. Sirius has been through a lot, like Azkaban, and his depression should be portrayed realistically. For example, his mood swings, self - doubt, and isolation. Remus should also be in - character, showing his loyalty and love for Sirius in a way that is true to the original series.
One common theme is friendship - turned - love. Since they start as friends as part of the Marauders, a lot of fanfics explore how that friendship deepens into romantic love over time. Another theme is loyalty. They've been through a lot together, and the fics often show how they remain loyal to each other no matter what.
